Technology's impact on the building industry can be seen in the superslim towers that would have been structurally inconceivable even a decade ago as well as the photorealistic renderings that we've come to expect from starchitects. On a smaller scale, fabrication technology and cheap microcontrollers have changed the game for building sales tools. SkyriseCities recently stopped by Myles Burke Architectural Models, where a high-tech model for The World Towers in Mumbai was being assembled.

I was in Mumbai in August of 2014 - the tower was tall, but still far from topping out. I never got close enough to make a proper estimate or floor count.

Fast-forward now, and I'm back in Mumbai to celebrate New Year's. I was shocked to see the tower still, seemingly, a fair ways from topping out. Like last time, I didn't get a close look, but other towers have been finished and new ones are sprouting with considerable speed.

Perhaps there's a problem with financing? Demand? Labor? I wish I knew, but the Mumbai luxury market is totally opaque to me, just like the skyline on a humid day.
